It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.

Cleaning device, such as robot of sweeping floor, has gradually got into people's life, however current machine of sweeping floor is only had the function of sweeping floor more, like set up the dish brush on cleaning device, through driving the rotation of dish brush, realize cleaning ground, and this kind of cleaning device's cleaning performance is relatively poor, still need to make a round trip to clean to wait to clean the region simultaneously, consequently also comparatively consuming time. Of course, cleaning devices with sweeping and mopping functions are also available on the market, but such cleaning devices can leave stains such as liquid on the floor, resulting in undesirable cleaning effects.

In order to further improve the cleaning effect, the embodiment of the application provides a cleaning device, which is provided with a scraping strip in abutting connection with a surface to be cleaned besides sweeping and mopping, and the scraping strip is used for removing water and dust on the surface to be cleaned along with the movement of the cleaning device so as to improve the cleaning effect.

Specifically, the scraping strip of the cleaning device may be disposed at the rear of the cleaning component of the cleaning device, so as to scrape the surface to be cleaned after the cleaning component cleans the surface to be cleaned, so as to remove stains (also referred to as water stains) such as liquid or fixed stains on the surface to be cleaned, thereby improving the cleaning effect.

The scraping strip can remove water and dust to improve the cleaning effect, but the scraping water easily causes water dust to leak from the side of the two ends of the scraping strip, so that the cleaning effect of the cleaning device is affected. It should be noted that, the surface to be cleaned is an object to be cleaned by the cleaning device, specifically, for example, a floor, a glass surface, or a wall surface, and for convenience of understanding, the floor will be described as an example of the surface to be cleaned in some embodiments.

Therefore, the embodiment of the application provides another cleaning device, which aims to prevent water dust from leaking from the two end parts of the scraping strip, thereby improving the cleaning effect of the cleaning device.

Referring to fig. 1 and 2, fig. 1 and 2 show a structure of another cleaning device 100 according to an embodiment of the application, where the cleaning device 100 at least includes a scraper 11 and an air suction port 21, and the air suction port 21 is used to solve the problem of side leakage at the end of the scraper 11.

Specifically, as shown in fig. 1 and 2, the cleaning device 100 is provided with the scraping bar 11 and the suction inlet 21, wherein the suction inlet 21 is provided on the cleaning device 100, for example, on a bracket of the cleaning device 100, specifically may be provided in the cleaning device 100 near the scraping bar 11, and more specifically the suction inlet 21 may be provided near the middle of the scraping bar 11. When the cleaning device 100 uses the scraping strip 11 to scrape the surface to be cleaned, the suction port 21 brings the solid or liquid stains on the surface to be cleaned to the scraping area corresponding to the scraping strip 11 in a suction mode, and then the scraping strip 11 is used for cleaning. Therefore, by utilizing the matching of the scraping strip and the air suction inlet, water stains can be prevented from leaking from the two end parts of the scraping strip 11, and the cleaning effect of the cleaning device is improved.

Specifically, as shown in fig. 2, in the position where the suction port 21 is provided, the suction port 21 may be located at the front side of the scraper bar 11 in the moving direction of the cleaning device 100, which may also be referred to as the front. It will be understood, of course, that the suction opening 21 may also be provided at the rear side of the scraper bar 11 in the direction of movement of the cleaning device 100 for carrying, by suction, dirt, such as solids or liquids, on the surface to be cleaned towards the corresponding wiping area of the scraper bar 11.

As shown in fig. 3, when the cleaning device wipes a surface to be cleaned using the wiper 11, water stains accumulate in front of the wiper 11, and as the wiping time increases, water stains accumulate more, and water stain side leakage is more likely to form from both ends 101 of the wiper 11. Further, due to the water stain and the tension between the both end portions 101 of the wiper strip 11, the water stain may be laterally leaked to the wiping area that has been wiped, that is, the water stain may remain on the surface to be cleaned that has been cleaned. Therefore, the cleaning device which automatically plans the path or the cleaning device which requires the user to push the travelling is generally not used for cleaning the cleaned area, so that water stains left on the cleaned surface to be cleaned can seriously affect the cleaning effect and further affect the use experience of the user.

In fig. 3, the direction of movement indicated by the arrow is the direction of movement of the wiper strip 11, and the wiper strip 11 is generally driven by the cleaning device and can therefore also be understood as the direction of movement of the cleaning device. The front side of the wiper 11 in the moving direction of the cleaning device means the side of the wiper that is not wiped, i.e. the side of the wiper 11 that is to be wiped, and may also be referred to as the front side of the wiper 11; the rear side of the wiper strip 11 in the moving direction of the cleaning device refers to the side of the wiper strip 11 that has been wiped off, and may also be referred to as the rear of the wiper strip 11. The wiping area of the wiper strip 11 is the area of the wiper strip that can be wiped on the surface to be cleaned. That is, it can be simply understood that the wiper strip 11 divides the moving area of the cleaning device into a front and a rear.

The front side (front), rear side (rear), wiping area and direction of movement of the cleaning device of the wiper strip are understood with reference to this definition, unless otherwise specified.

It should be noted that, the moving direction may be understood as a forward direction of the cleaning device, for example, if the cleaning device needs to be pushed by a user, the moving direction may be understood as a corresponding direction when the user pushes the cleaning device forward; if the cleaning device is a self-moving device, the direction of movement is understood to be the direction of travel of the self-moving device, i.e. the main direction of travel when the cleaning device is cleaning a surface to be cleaned. Although the cleaning device may also retract or turn in different situations, in the embodiments of the present application, the moving direction of the cleaning device refers to the main running direction such as the advancing direction of the cleaning device, the advancing direction of the user, and so on.

It should be noted that, in the embodiment of the present application, the wiper strip 11, the suction port 21, and the cleaning member 32 may be referred to as a cleaning assembly.

In some embodiments, considering in combination the need for the suction opening 21 to carry the stain to the wiping area of the wiper strip 11 and how to carry the stain deposited by the wiper strip 11 to the trash box with the cleaning member 32, as shown in fig. 4, the distance of the wiper strip 11 from the cleaning member 32 may be set in the range of 1cm to 5cm. This distance range can make things convenient for clean part 32 to clear up the accumulational spot of scraping strip 11, has avoided appearing accumulational spot too much and has led to appearing the side leakage from scraping the both ends of strip, and then has improved cleaning performance.

In some embodiments, as shown in fig. 5, in order to effectively avoid side leakage at two ends of the scraping strip 11 to improve the cleaning effect, the air suction opening 21 may be disposed at a front side of the scraping strip 11 along the moving direction of the cleaning device 100, and the air suction opening 21 is located in the air guiding channel 320 formed by the scraping strip 11 and the cleaning component 32 of the cleaning device 100, and the side leakage at the ends of the scraping strip 11 may be better avoided by using the air suction opening 21 and the air guiding channel 320.

Since the scraping strip 11 is located at the rear of the moving direction of the cleaning device 100, the scraping strip 11 and the cleaning component 32 are abutted against the surface to be cleaned, the scraping strip 11 and the cleaning component 32 form the air guide channel 320, and the air guide channel 320 can strengthen the inner side flow of the wind direction scraping strip 11, so that the side leakage at the end part of the scraping strip 11 can be more effectively prevented.

In the embodiment of the present application, the number of the air suction openings 21 is at least one, and the at least one air suction opening 21 is close to the middle position of the scraping strip 11. Of course, it may be disposed at a position close to the middle of the wiper strip 11 and to the left or right.

For example, as shown in fig. 6 and 7, the cleaning device 100 may include one suction port 21, for example, which is located at a front side of the wiper strip 11 in the moving direction of the cleaning device 100 and near the middle position of the wiper strip 11. It will be appreciated that one suction opening 21 may also be located at the rear side of the scraper bar 11 in the direction of movement of the cleaning device 100. It should be noted that, although the effect of the scraper bar 11 disposed at the rear side along the moving direction of the cleaning device 100 may not be as good as that of the scraper bar disposed at the front side, the problem of side leakage at the end of the scraper bar 11 may be relatively solved, so as to further improve the cleaning effect.

Of course, the number of the air suction openings 21 is plural, and the plural air suction openings 21 are arranged in a row, and as shown in fig. 8, the cleaning device 100 includes three air suction openings 21, and the three air suction openings 21 are arranged in a row and located at the front side of the scraper bar 11 and near the middle position of the scraper bar 11. The plurality of air inlets are arranged in rows, so that the cleaning effect can be improved.

The suction opening 21 may be disposed opposite the surface to be cleaned, for example, opposite the surface to be cleaned, as shown in fig. 2 and 6. It is of course also possible to provide the suction opening 21 with a predetermined inclination with respect to the surface to be cleaned, i.e. not in a facing manner.

In the embodiment of the present application, the suction of the suction port 21 may be implemented by a blower (such as an exhaust fan). Illustratively, the cleaning apparatus, for example, further comprises at least one air duct structure coupled to the intake 21 and at least one fan coupled to the air duct structure, whereby the fan provides a source of air to the intake 21 via the air duct structure. It will be appreciated that the provision of a wind source to the inlet scoop 21 is not limited to the manner in which the fan and duct arrangement is provided, for example, the wind scoop of the fan may also be provided as the inlet scoop 21. It is of course also possible to provide the air intake 21 with a combination of several fans and an air duct structure.

In some embodiments, the air duct structure 22 may be configured to have a predetermined inclination angle with respect to the surface to be cleaned, so that the air intake 21 has a certain inclination angle with respect to the surface to be cleaned. For example, wind can be induced to downwards wind from the inclined upper direction of the scraping strip 11 so as to bring water stain to the middle position of the scraping strip 11, and side leakage at the end part of the scraping strip 11 can be better avoided.

It should be noted that, the air duct structure 22 may be a pipeline, where the air suction port 21 may be connected to the pipeline, and the plurality of air suction ports 21 may share the pipeline. It will also be appreciated that the conduit may be threaded into the wiper strip assembly 10, such as the wiper strip 11, wherein the conduit may also be provided on the front or rear side of the wiper strip 11. Therefore, the fan can also be located in front of or behind the scraping strip 11, and when the fan is located behind the scraping strip 11, the air duct structure 22 penetrates through the scraping strip 11.

In an embodiment of the present application, as shown in fig. 5, 6, 7 and 8, the cleaning member 32 may include a first endless cleaning belt 321 and a second endless cleaning belt 322, the first endless cleaning belt 321 and the second endless cleaning belt 322 may clean a surface to be cleaned, the first endless cleaning belt 321 and the second endless cleaning belt 322 may be rotated by a driving member, and garbage on the surface to be cleaned may be transferred to the recovery container 31 (may also be referred to as a garbage box).

It will be appreciated that the cleaning element 32 may also comprise an endless cleaning belt, such as a first endless cleaning belt 321, or a second endless cleaning belt 322.

In other embodiments, the cleaning element 32 may also include a sweeping element or a mopping element, such as a sweeping brush, a roller brush, a double roller brush, etc., and the mopping element may be a mop, a roller wrapped with cleaning fleece, a cleaning belt, etc., and the sweeping brush may include a disk brush, a side brush, etc. Of course, the cleaning member 32 may also include a combination of both sweeping and mopping members.

In summary, various cleaning apparatuses 100 according to the embodiments of the present application include the scraping strip 11 and the suction inlet 21, where the scraping strip 11 and the suction inlet 21 are disposed on the cleaning apparatus 100, for example, are disposed on the housing 30 of the cleaning apparatus 100, and the housing may be an outer housing or an inner housing of the cleaning apparatus 100, for example, a support of the cleaning apparatus 100, and the support is disposed in the outer housing for disposing the suction inlet 21 or the scraping strip 11, and the support may be other components of the cleaning apparatus, such as a cleaning component and a recycling container. When the cleaning device 100 uses the scraping strip 11 to scrape the surface to be cleaned, the air suction port 21 is used for bringing the solid or liquid of the surface to be cleaned to the scraping area corresponding to the scraping strip 11, and then the side leakage at the end part of the scraping strip 11 is avoided by utilizing the cooperation of the air suction port 21 and the scraping strip 11, so that the cleaning effect can be improved.

In an embodiment of the present application, the scraping strip 11 may be provided on the cleaning device 100 by the fixing member 12, in particular, the scraping strip 11 may be mounted on the fixing member 12 and then mounted on the housing of the cleaning device 100 by the fixing member 12, wherein the scraping strip 11 and the fixing member 12 constitute the scraping strip assembly 10, as shown in fig. 9.

In some embodiments, as shown in fig. 9, the air vent 102 may be formed in the scraping strip 11, where, because the scraping strip 11 and the cleaning component 32 of the cleaning device 100 form the air guiding channel 320, which is equivalent to providing the air vent 102 in the air guiding channel 320, the air flow in the air guiding channel 320 can be more convenient, and thus, the side leakage at the end of the scraping strip 11 can be more effectively prevented.

It will be appreciated that the vent 102 may also be provided in the mount 12. The number of the ventilation holes 102 may be one or more, and the shape of the ventilation holes 102 may be circular, square or rectangular, or other shapes, which are not limited herein.

Specifically, the vent hole 102 may be provided at a middle position of the wiper strip 11, or the vent hole 102 may be provided at a middle position of the mount 12. Of course, the vent 102 may be provided in other locations on the wiper strip 11 or the mounting member 12.

In some embodiments, as shown in fig. 10, the fixing member 12 includes a first fixing member 121 and a second fixing member 122, and the first fixing member 121 and the second fixing member 122 are used to clamp and fix the wiper strip 11. Utilize first mounting 121 and second mounting 122 centre gripping to scrape strip 11, because first mounting 121 and second mounting 122 can dismantle, and then make things convenient for the scraping strip 11 of damage to be changed in the future, improve clean effect.

In some embodiments, as shown in fig. 10, the first fixing member 121 further includes a first clamping groove 1210, and the second fixing member 122 further includes a second clamping groove 1220, and the first clamping groove 1210 and the second clamping groove 1220 are used to clamp the fixing portion 113 of the wiper strip 11. This can increase the stability of the wiper strip 11, so that loosening does not occur when the wiper strip 11 is used for removing liquid, and thus the cleaning effect can be improved.

Of course, it is understood that one of the first fixing member 121 and the second fixing member 122 may include a clamping groove, for example, the first fixing member 121 may further include the first clamping groove 1210, and the stability of the wiper strip 11 may be improved by one clamping groove.

It should be noted that the scraping strip 11 and the fixing member 12 may be integrally designed. For example, the fixing portion 113 of the wiper 11 is made of hard material, and the wiper portion 114 is made of soft material, wherein the fixing portion 113 may be configured as the fixing member 12, i.e., the fixing portion 113 may be understood as a fixing member. Thus, in embodiments of the present application, the wiper strip assembly 10 may include multiple components, such as the wiper strip 11 and the fastener 12, but may also include only one component of the wiper strip 11.

As shown in fig. 10, the wiper 11 may include a fixing portion 113 and a wiper portion 114, the wiper portion 114 extending from the fixing portion 113, the wiper portion 114 being for contacting a surface to be cleaned for wiping stains on the surface to be cleaned. Wherein, the thickness of the fixing portion 113 may be greater than that of the wiping portion 114, so that the fixing of the wiper 11 is facilitated, and the toughness of the wiper 11 during wiping may be increased, thereby improving the wiping effect.

In some embodiments, the wiper strip 11 may be made of a soft material to enhance cleaning. In some embodiments, the wiper 11 may be made of the same material, but may be made of a different material, such as one material for the fixing portion 113 and another material for the wiper portion 114, wherein the hardness of the fixing portion 113 is greater than the hardness of the wiper portion 114.

In some embodiments, in order to enhance the cleaning effect of the wiper, the portion of the wiper 114 that contacts the surface to be cleaned may also be provided in a saw-tooth shape, and specifically, the bottom or front side of the wiper 114 may include a saw-tooth shape.

In some embodiments, as shown in fig. 11, the wiper strip 11 may include a plurality of sub-wiper strips 110 having an elongated shape, and the plurality of sub-wiper strips 110 constitute the wiper strip 11. When the wiper strip 11 including the plurality of sub-wiper strips 110 is used to wipe the ground, the cleaning effect of the ground can be improved, the combination form of the wiper strips 11 is enriched, and the user can decide how many sub-wiper strips 110 to use for combination, so that the cleaning effect can be improved, and the user experience can be improved.

In some embodiments, as shown in fig. 12a and 12b, the scraping strip 11 includes a plurality of elongated sub-scraping strips 110, and the plurality of sub-scraping strips 110 form the scraping strip 11, wherein the plurality of sub-scraping strips 110 have different heights, and when the plurality of sub-scraping strips 110 are mounted on the fixing member 12, the tops of the plurality of sub-scraping strips 110 are flush, and the tops are one end mounted on the fixing member 12, so that the distances from the bottoms of the plurality of sub-scraping strips 110 to the surface to be cleaned are different. That is, when the surface to be cleaned is not cleaned, the distances from the bottoms of the plurality of sub-wiper strips 110 to the surface to be cleaned are different, wherein the distance corresponding to the front sub-wiper strip 110 in the moving direction of the cleaning device 100 is greater than the distance corresponding to the rear sub-wiper strip 110 (h 1 > h2 > h 3), as shown in fig. 12 b. Therefore, stains on the ground can be cleaned by using different forces, and the cleaning effect can be further improved.

In some embodiments, the cleaning device 100 may further include an encircling scraper bar 11, as shown in fig. 13a, where, illustratively, the encircling scraper bar 11 specifically includes a strip-shaped body 111 and encircling arms 112, two encircling arms 112 extend from two sides of the strip-shaped body 111, the strip-shaped body 111 is generally elongated, the encircling arms 112 have a certain radian, and the encircling direction of the encircling arms 112 faces the moving direction of the cleaning device, and may also be understood as that the encircling direction of the encircling arms 112 faces the front side of the scraper bar 11. The encircling wiper strip 11 is generally designed to be larger, i.e. the area covered by the encircling wiper strip 11 is larger than the area covered by the cleaning element of the cleaning device, so that the cleaned area of the cleaning element can be wiped. However, the both end portions 101 of the encircling wiper strip 11 also have water spot side leakage, and the problem of water spot side leakage cannot be truly solved, but the cleaning effect is improved by repeated wiping.

In addition, when the encircling type scraping strip 11 is used for scraping the surface to be cleaned, the bottom of the scraping strip 11 needs to be propped against the surface to be cleaned, as the encircling arm 112 of the scraping strip 11 has a certain radian, when the surface to be cleaned is propped against, the contact part of the encircling arm 112 and the surface to be cleaned can form a warping angle 1121, and particularly as shown in fig. 13b, the formed warping angle 1121 can also cause water stains to be omitted on the surface to be cleaned which is already scraped, so that the problem of end side leakage exists for the encircling type scraping strip, and the region corresponding to the encircling arm can also be omitted, so that the cleaning effect is affected.

It should be noted that, while the wiper 11 shown in fig. 13b forms one rake angle 1121, in actual situations, one or more rake angles 1121 may be formed, where the sizes of the rake angles 1121 may be the same or different.

For the encircling scraping strip 11, the cleaning device provided by the application not only can solve the problem of side leakage at two ends of the encircling scraping strip 11, but also can solve the problem of spot omission caused by the warping angle formed by the encircling arm 112, and further can improve the cleaning effect of the cleaning device.

It should be noted that, according to the analysis of the encircling type scraper bar 11, since the two encircling arms 112 of the encircling type scraper bar 11 easily form a rake angle, in the embodiment of the present application, a combination of the scraper bar 11 having a substantially long shape and the air intake 21 can be used, a better cleaning effect can be obtained, and the cost can be reduced by using the long scraper bar.

In an embodiment of the present application, as shown in fig. 5, the cleaning device 100 further includes a driving mechanism 40, which may also be referred to as a driving mechanism, where the driving mechanism 40 is connected to the wiper strip assembly 10, and specifically, the driving mechanism 40 is connected to the fixing member 12; the driving mechanism 40 is used for adjusting the distance between the scraping strip 11 and the surface to be cleaned, so that the scraping strip 11 can be lifted by the driving mechanism 40 to be separated from the surface to be cleaned when the cleaning device 100 does not need to remove liquid.

Since the wiper strip 11 and the attachment 12 can also be of unitary design, it is understood that the drive mechanism 40 is coupled to the wiper strip assembly 10, either to the attachment 12 or to the wiper strip 11.

In some embodiments, the driving mechanism 40 may specifically include a lifting mechanism and a rotating mechanism, where the lifting mechanism is connected to the wiper strip assembly 10, and may specifically be connected to the fixing member 12 of the wiper strip assembly 10, for driving the wiper strip assembly 10 to rise or fall; the rotating mechanism is connected with the scraping strip assembly 10 and is used for driving the scraping strip assembly 10 to rotate.

Wherein, the lifting mechanism comprises a power source for respectively realizing the lifting or descending of the scraping strip assembly 10; the rotation mechanism also includes a power source for effecting control of the rotation of the wiper strip assembly 10.

For example, the lifting mechanism includes a first motor and a lifting structure, where the first motor is connected to the lifting structure, specifically, for example, in a meshing manner, and the first motor drives the lifting structure to rise or fall, and the lifting structure is connected to the fixing member 12, so as to drive the scraping strip 11 to rise or fall.

Illustratively, the rotation mechanism includes a second motor that may be directly coupled to the rotational axis of the wiper strip assembly 10 for driving the wiper strip assembly 10 in rotation relative to the rotational axis. The rotation mechanism may of course also comprise a first gear and a second gear in a toothed connection, the first gear being connected with the rotation axis of the wiper strip assembly 10, the second gear being connected with a second motor, the second motor driving the wiper strip assembly 10 to rotate relative to the rotation axis via the second gear and the first gear. Since the wiper strip assembly 10 may be first lifted up to rotate, or first rotated to lift up, the rotating mechanism may be disposed on the wiper strip assembly 10, and then lifted up and down together with the wiper strip assembly 10, and after the wiper strip assembly 10 is lifted up to a preset position, the wiper strip assembly 10 is driven to rotate by the second motor of the rotating mechanism.

Of course, there are many other implementations of the drive mechanism 40 for controlling the raising, lowering and rotation of the wiper strip assembly 10, and this is not limiting.

In the embodiment of the present application, in order to make the size of the product more compact and miniaturized, the driving mechanism 40 may be designed to use only one power source (such as one motor), i.e., the lifting and rotation of the wiper strip assembly 10 may be controlled, thereby simplifying the control logic and saving electricity.

Specifically, as shown in fig. 14 and 15, the driving mechanism 40 includes a driving assembly 41, a link structure 42, and a tension member 43, wherein the driving assembly 41 is used for providing a driving force, the link structure 42 connects the driving assembly 41 and the wiper strip assembly 10, the driving assembly 41 drives the wiper strip assembly 10 to move through the link structure 42, and the tension member 43 is connected with the wiper strip assembly 10 for providing a tension force for the wiper strip assembly 10. Under the combined action of the link structure 42 and the tension member 43, the wiper strip assembly 10 is enabled to move toward the cleaning member 32, such as by driving the wiper strip assembly 10 to a predetermined position and rotating a predetermined angle, so that the wiper strip 11 of the wiper strip assembly 10 abuts the cleaning member 32.

Similarly, since the wiper strip 11 and the mounting member 12 may be integrally formed, it is understood that the tension member 43 may be coupled to the wiper strip assembly 10, either to the mounting member 12 or to the wiper strip 11.

The preset position can be designed according to actual requirements, for example, the common obstacles on the ground, such as carpets, need to be avoided when the preset position is lifted, so that a user can conveniently switch between a liquid removing mode and a liquid removing mode without using the cleaning device according to different scenes. The preset angle can also be designed according to actual requirements, for example, the height of the scraping strip 11 is combined to design the scraping strip 11 to rotate by the preset angle, so that the scraping strip 11 can be abutted against the cleaning component 32 of the cleaning device 100, and then self-cleaning of the scraping strip 11, namely, a self-cleaning mode of the scraping strip or a self-cleaning function of the scraping strip can be realized. The liquid removing mode is a mode of cleaning the floor by using the scraping strip.

In some embodiments, the drive mechanism 40 may include a drive assembly 41 and a linkage structure 42 without the use of a tension member 43. The driving component 41 is used for providing driving force, the connecting rod structure 42 is connected with the driving component 41 and the scraping strip component 10, the driving component 41 drives the scraping strip component 10 to move through the connecting rod structure 42, and the movement is that the driving component 41 drives the scraping strip component 10 to move, particularly to rise after rotating firstly through the connecting rod structure 42 due to the fact that the pulling force piece 43 does not work together.

It should be noted that, although the driving mechanism 40 may also be capable of driving the rotation and the lifting of the wiper strip assembly 10 without using the tension member 43, the rotation and lifting process is opposite to the process of using the tension member 43, and the tension member 43 is used to lift and then rotate. If the rotation is first followed by the ascent, it may have an effect on the switching of some modes of operation. For example, the cleaning device 100 needs to be designed to have a self-cleaning function of the wiper strip, the wiper strip 11 needs to be abutted against the cleaning member 32, the cleaning member 32 is utilized to clean the wiper strip 11, and the wiper strip 11 is inevitably blocked from rising by rotating and abutting against the cleaning member 32, and meanwhile, the wiper strip 11 may abut against the surface to be cleaned during rotation, so that a large driving force is required. Meanwhile, when the liquid removing mode is switched, for example, when the liquid removing mode is switched from the liquid removing mode to the liquid removing mode, the tension piece 43 is not used, the scraping bar assembly 10 can be rotated first and then ascended, but when the liquid removing mode is used, the scraping bar 11 of the scraping bar assembly 10 is abutted with the ground, and the abutted friction force does not utilize the rotation of the scraping bar 11, so that a large moment is required to be output by the motor of the driving assembly 41, and the motor of the driving assembly can be burnt when the situation is serious.

In some embodiments, as shown in fig. 16, the driving assembly 41 includes a motor 411 and a rotating member 412, the motor 411 may be provided on the housing 30 (bracket) of the cleaning device 100, the rotating member 412 is connected with a rotor of the motor 411, and the rotating member 412 can be rotated forward and backward by driving of the motor 411. The rotating member 412 is further configured to be connected to the link structure 42 to move the link structure 42.

Specifically, as shown in fig. 16, and in combination with fig. 15, the housing 30 may include a motor mounting area 301 thereon, the motor mounting area 301 being configured to mount the motor 411, and the motor 411 being mounted on the stand of the cleaning device 100, i.e., the motor mounting area 301, specifically by a motor mount 413.

In some embodiments, as shown in fig. 16, the linkage structure 42 includes a first linkage 421 and a second linkage 422, the first linkage 421 including opposite first and second ends, the first end of the first linkage 421 being coupled to the drive assembly 41, and in particular, being connectable to the rotary member 412 of the drive assembly 41; the second link 422 includes opposite first and second ends, the second end of the first link 421 being rotatably coupled to the first end of the second link 422, the second end of the second link 422 being rotatably coupled to the wiper strip assembly 41. The operating state of the link structure 42 can be referred to hereinafter with respect to the state of the wiper strip assembly 10.

In some embodiments, as shown in fig. 15, one end of the tension member 43 is connected to the bracket of the cleaning device 100, and the other end of the tension member 43 is connected to the wiper strip assembly 10, and may be specifically connected to the fixing member 12 of the driving assembly 10; wherein the pulling direction provided by the pulling member 43 is disposed at an angle to the rising direction of the wiper strip assembly 10. It should be noted that, in addition to the connection with the bracket of the cleaning device 100, one end of the tension member 43 may be connected to other components of the cleaning device 100, such as a cleaning component or a garbage can.

Specifically, as shown in fig. 16, the fixing member 12 is further provided with a first connecting member 123, and the other end of the tension member 43 is connected to the first connecting member 123. Facilitating the installation or removal of the tension member 43.

The tension member 43 is a member that can provide tension, and for example, the tension member 43 includes a spring, a rubber band, or the like. The number of tension members 43 may be one or more. As shown in fig. 15 and 16, for example, the number of tension members 43 is two, wherein the link structure 42 is located between the two tension members 43, thereby providing a relatively balanced tension. It should be appreciated that the tension provided by the tension member 43 not only provides the lifting power for the wiper strip assembly 10, but also cooperates with the linkage structure 42 to enable the wiper strip assembly 10 to be lifted to a predetermined position and rotated by a predetermined angle.

The above-mentioned ascending and then rotating process, or the ascending process after rotating, does not mean that there is no rotation at all in the ascending process, or there is no ascending in the rotating process, but there is a slight rotation accompanying the ascending process, but the ascending is mainly represented as ascending; the rotation is accompanied by a slight increase, and is mainly represented by rotation. For example, a process that mainly shows rising and then mainly shows rotation is referred to as a rising-before-rotation process, and a process that mainly shows rotation and then mainly shows rising is referred to as a rotation-before-rising process.

In some embodiments, as shown in fig. 16, the link structure 42 further includes a mounting seat 423, where the mounting seat 423 is mounted on a support of the cleaning device 100, and the first end of the first link 421 is rotatably connected to the mounting seat 423, so as to increase the rotational stability of the first link 421.

In some embodiments, as shown in fig. 16, the wiper strip assembly 10 may also include a second connector 124, or it may be understood that the fixing member 12 includes a second connector 124, where the second connector 124 is disposed inside the upper end of the wiper strip assembly 10, and in particular, may be disposed inside the upper end of the fixing member 12; the second end of the second link 422 is rotatably coupled to the wiper strip assembly 10 by the second coupler 124. Wherein the second connecting member 124 may be detachably connected to the fixing member 12 or may be integrally designed with the fixing member 12.

It should be noted that, the upper end of the wiper strip assembly 10 is an end of the wiper strip assembly 10 away from the surface to be cleaned, specifically, an end of the fixing member 12 away from the surface to be cleaned, and the inner side of the upper end is a side of the upper end, which is close to the cleaning member 32 of the cleaning device 100. The power of the driving assembly 41, in particular the motor, can be saved, and the rotation of the scraper assembly can be controlled by outputting smaller moment.

In some embodiments, as shown in fig. 5 and 15, the cleaning device 100 includes a guide 44, the guide 44 being coupled to the wiper strip assembly 10, the guide 44 being configured to guide movement of the wiper strip assembly 10, such as to guide lifting and rotation of the wiper strip assembly 10. The guide 44 may include a square groove or a waist groove. The guide 44 may provide for a better fit with the linkage structure 42 or tension member 43 to provide motion control of the wiper strip assembly 10.

Specifically, the number of the waist-shaped grooves is two, and the two waist-shaped grooves are opened on the bracket of the cleaning device 100 and are opposite. The connecting posts 125 are disposed at two side ends of the wiper strip assembly 10, and specifically, the connecting posts 125 are disposed at two side ends of the fixing member 12. Each of the waist-shaped grooves is rotatably provided through one of the connection posts 125, thereby guiding the movement of the wiper strip assembly 10, including elevation and rotation guides, etc.

In an embodiment of the present application, the driving mechanism 40 may adjust the distance between the wiper 11 and the surface to be cleaned, and drive the wiper 11 to move toward the cleaning member of the cleaning device 100. Specifically, through the design of the connecting rod structure 42, the scraper assembly 10 can be driven to rise and rotate and the scraper assembly 10 can be driven to descend, so that the scraper assembly 10 has three states, namely a descending state, a rising state and a rotating state.

In the lowered state, as shown in fig. 17a and 17b, the driving mechanism 40 drives the wiper strip assembly 10 to descend, the wiper strip 11 of the wiper strip assembly 10 presses against the floor, and the floor can be wiped as the cleaning device 100 moves, that is, the cleaning device 100 performs the liquid removing mode. It should be noted that, due to the design of the link structure 42, the wiper strip 11 may be inclined to the rear side of the wiper strip 11 during the descent, i.e., the inclination angle θ in fig. 17 b. Therefore, when the scraping strip 11 is pressed against the ground, the scraping part of the scraping strip 11 can be fully contacted with the ground, and the cleaning effect is further improved.

In the raised state, as shown in fig. 18a and 18b, the driving mechanism 40 drives the wiper strip assembly 10 to rise, the wiper strip 11 of the wiper strip assembly 10 is separated from the floor, and the cleaning device 100 can be understood as canceling the liquid removing mode.

As shown in fig. 19a and 19b, the driving mechanism 40 drives the wiper strip assembly 10 to rise to a preset position, specifically, a top end position of the guide (waist-shaped groove) 44, and continues to drive the wiper strip assembly 10 to rotate, so that the wiper strip 11 abuts against the cleaning member 32 (the first annular cleaning belt 321), and the cleaning member 32 is utilized to perform self-cleaning on the wiper strip 11, which is understood as the cleaning device 100 executing the wiper strip self-cleaning mode.

In some embodiments, the cleaning device 100 has a liquid removing mode in which the driving mechanism 40 drives the scraping bar 11 to press against the surface to be cleaned, and the surface to be cleaned is scraped to remove liquid from the surface to be cleaned. Specifically, the liquid removing mode may be selected by setting a mode key on the cleaning device 100, or by setting a touch screen, and displaying the liquid removing mode on the touch screen for the user to select.

For example, in one scenario, if the user wants to use the liquid removing mode of the cleaning device 100, the liquid removing mode may be selected through the mode button, and when the cleaning device 100 is in the liquid removing mode, the driving mechanism 40 drives the scraping strip 11 to press against the surface to be cleaned, so as to perform liquid removing cleaning on the surface to be cleaned. If the user takes the liquid removal mode, the wiper strip 11 can be lifted off the surface to be cleaned by the drive mechanism 40.

For another example, if a floor surface is encountered where the liquid removal mode is unavailable, such as carpeted, the user may cancel the liquid removal mode and the drive mechanism 40 lifts the blade 11 off of the surface to be cleaned when the cleaning device 100 is in the liquid removal mode.

In some embodiments, the drive mechanism 40 is also used to rotate the lifted wiper strip 11 such that the wiper strip 11 abuts the cleaning member 32 of the cleaning device 100 to achieve self-cleaning of the wiper strip 11 with the cleaning member 32. Therefore, the scraping strip does not need to be manually cleaned by a user, and the experience of the user is improved.

The cleaning device 100 has a self-cleaning function for the wiper strip 11, i.e., cleaning of the wiper strip 11 is performed by the cleaning member 32. The self-cleaning function can perform self-cleaning on the scraping strip 11 in the working process of the cleaning device 100, wherein the working process is the process of cleaning the surface to be cleaned; naturally, the wiper strip 11 may be self-cleaned when the cleaning device 100 is not in operation.

For example, in one scenario, when the cleaning device 100 is used to remove liquid from the floor, if the floor has small hard objects, such as rice grains, the small hard objects may adhere to the wiping portion 114 of the wiper 11, thereby affecting the liquid removal effect of the wiper 11. If the user finds that the liquid removing effect is not good, the user can select the self-cleaning function of the cleaning device 100 to clean the scraper bar 11, thereby improving the liquid removing effect.

As another example, in another scenario, such as when the user begins to use the cleaning device 100, such as when the user is concerned that the wiper strip 11 may be stuck with debris; or when the user finishes using the cleaning device 100, there is a fear that the scraping strip 11 may be stuck with garbage to affect the next liquid removing effect, and the user can select the self-cleaning function of the cleaning device 100 to clean the scraping strip 11, thereby improving the liquid removing effect.

When the driving mechanism 40 is used to drive the wiper strip assembly 10 to move and contact the cleaning component of the cleaning device, if the air suction port 21 is disposed on the front side of the wiper strip 11, the air suction port 21 may be designed not to block the movement of the wiper strip assembly 10, for example, the air suction port 21 may be controlled to rise.

The cleaning device provided by the above embodiments at least comprises the scraping strip and the air suction inlet, when the cleaning device uses the scraping strip to scrape the surface to be cleaned, the air suction inlet is used for bringing the solid or liquid of the surface to be cleaned to the scraping area corresponding to the scraping strip, the scraping strip is used for cleaning the stains on the surface to be cleaned, and meanwhile, the side leakage at the end part of the scraping strip of the cleaning device can be avoided, so that the cleaning effect of the cleaning device is improved.

While the application has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
